1. Obtain information about your topic from our textbook and by going to search engines such as Google. Keep the following in mind for each section as you do your work:
Use sites that end in .edu, or .gov for the best information. Your sites for information must satisfy this criteria.
Make bulleted lists only in the table. You may not use complete sentences. This is to help you avoid accidental plagiarism. When you go to write your rough draft and final copy, you can use your bulleted list as you put the information into your own words.
You need to include at least three relevant illustrations and include an explanation of your illustration in the written work that you post. These may be illustrations you make or some from the web (don't have to end in .edu or .gov; must include citations).
Use either 1 video you find or a video you make to help explain your part of the project. Flip cameras are available for you to use if you need to borrow one. You may also use Photobooth or Quicktime movie to make your video.
Include at least one experiment/activity. Your classmates will be doing this experiment/activity. Make sure it adds to the understanding of the content. The activity may be hands-on or a link to one on the web.
2. Write about 100-150 words on each of the required topics listed above. Use a word processor to save your work.
Be sure that in all work that you do in this course, that you use entirely, 100% your own wording. Using your own wording is very important as part of the learning process.
As you make your postings, you need to list a working web page link for any locations that you use in getting your information or illustrations. Be sure to list the exact page that you read, not the overall homepage for a website. Also, be sure to write http:// just before the www web address.
3. Always do your work in a processing program on your own computer. Then, cut and paste your own written work from your own word processor into the Team Wiki Making Progress on our Project page. If there is a glitch in your connection while you are working, you will not lose your work this way!
How You Will Be Evaluated:
This assignment is worth 20 points. To receive the points, you need to assist in subdividing the topic within your Team Wiki area, post to the Team Wiki at least 100 words of material that you researched and composed 100% in your own wording, post your illustrations with a relevanat explanation of the illustration, and post any web addresses used in your research, your writing, and illustrations not made by you.
Let's begin!
Insert your research below. The table will expand as needed. Remember to refer to the objectives on the first page for guidance. You might even want to copy and paste each objective into the table so you can determine who is responsible for each.

Key Terms:
Electric Charge: an electrical property of matter that creates electric and magnetic forces and interactions.
Electric conductor: a material in which charges can move freely and that can carry an electric current.
Electrical Insulator: a material that does not transfer current easily.
Electric Force: the force of attraction or repulsion between objects due to charge.
Electric Field: A region in space around a charged object that causes a stationary charged object to experience an electric force.
Conductors allow electric charges to move freely.
Insulators don't allow electric charges to transfer easily.
Electric charge builds up when two objects touch and move across each other.
When your body has electric charge buildup and you touch something metal, the electric charges go to the door and you feel a shock.
Protons and electrons are what make up electricity.
Same repel, opposite attract.
Conductors surrounded by a insulator make a more safe and efficient model.
A charged particle produces an electrical field will experience an electric force.
An electrical force for example: “An attraction of tissue paper to a negatively charged comb and the repulsion of the two balloons are examples of electric force.” When two things are charged differently, one positive and one negative, they attract.
A positive electric field will have lines(from page 535 in the textbook) will have lines pointing out around the positive charge itself. A negative force field will have all the lines point towards the negative charged particle.
Electric field lines never cross another one’s path.
Electric forces hold the parts of an atom together, even though we cannot see it.
Without electrical forces and atoms, life itself wouldn’t exist.
electrical potential energy- the ability to move an electric charge from one point to another
potential difference-between any two points, the work that must be done against electric forces to move a unit charge that must be done against electric forces to move a unit charge from one point to the other
cell- a device that is a source of electric current because of a potential difference, or voltage, between the terminals
current- the rate that electric charges move through a conductor
resistance- the opposition posed by a material or a device to the flow of current
an electric charge has potential energy
a negative charge will move away from another negative charge
potential difference measured in volts, SI unit V
potential difference is the change in the electrical potential energy of a charged particle/the change occurs when the charge moves from one place to another
Voltage for batteries can range from 1.5 to 12 volts
Batteries change chemical energy to electrical energy
one positive and negative terminal
batteries have electrolytes
electrolytes conduct electricity
When a switch is turned on electrodes move from the positive terminal to the negative one
negative charges moving one way are the same as a positive charge moving the other way
electrical appliances take 120V
light bulbs can range from 40 to 100W
a 40W bulb has more resistance than a 100W bulb
you find resistance by calculating current and voltage
resistance = voltage current
SI unit for resistance is ohm
A resistor is a conductor that helps control current
Electrons go through conductors easily
metals are good conductors
Superconductors let all electron go through
Ex. niobium, tin, and mercury
Semiconductors
can be conductors or insulators in different states
examples
silicon
germanium
Insulators
don’t allow current to leave
earth insulates when current goes to it (grounded)
current needs moving charges
current unit-ampere
electrons are attracted to positive terminals
The fan is using the electric current from the battery to move. The current goes from the positive terminal to the fan and back to the negative terminal.
Insulators are on outside of wires so we don't get shocked
The switch is turned on and the current comes from the battery(+) through the switch to the light bulb and back to the battery(-)
1. Use a knife to make cuts 6 cm apart Put a copper strip in one and a zinc strip in the other
2.Use two lengths of insulated copper wire that is the same size, connect both to a galvanometer 3. Put one wire on the copper strip and the other on the zinc strip Record reading for zinc-copper cell
4.Use different kinds of metals for strips and compare readings
